In fact when the style's key is different between 2 cells the converter is called, but if the style is the same, the converter is not called.

And that is a big issue for me.

For example if a have :

- a cell with style : "styleDispo0" the cellcontrol will have the good background and the image will be displayed according to the converter result (visible or not visible)

- then if the cell just below the first one has a style : "styleDispo10" the background is different, and the image will also be displayed (or not) according to the converter's result.

So 2 differents style => 2 differents result => no problem

But if I have the following cases :

- a cell with style : "styleDispo0" the cellcontrol will have the good background and the image will be displayed according to the converter result (so that is the same behaviour)

- then if the cell just below the first one has the same style : "styleDispo0" the background is the same BUT the image will also be the same WHILE I hoped the converter will also be called one more time because the image should be the same.

So 1 different style => only 1 result (while the visibility behaviour is binded with a converter)

So is there any solution to force the style to reload all the binded value and at the end recompute the converter result ?

The best way for us to assist you is if you provide a small isolated sample that we can run and use for debugging locally. If you are unable able to provide an isolated sample I may be able to give suggestions if you provide the code for your page.

I realize a poc about the issue you will find 2 images in the folder. It is the same data on 2 differents run. The first one un do a full screen in the second run I scroll down before doing the full screen. that is the only difference
